Acclaimed director Steven Soderbergh's next film, a thriller titled "Unsane," will see a wide theatrical release next spring, despite the fact that it was filmed entirely on an iPhone.

"Unsane" is currently scheduled to hit theaters on March 23, 2018, according toDeadline. Soderbergh will reportedly be self-distributing the film through his own company, Fingerprint Releasing, in collaboration with Bleecker Street.

Details on "Unsane" have slowly trickled out in recent months, including the fact that the film was shot in secret and entirely on Apple's iPhone, according to Entertainment Weekly. The film stars Claire Foy, Joshua Leonard, Jay Pharaoh, Juno Temple, Aimee Mullins, and Amy Irving, with Pharoah describing the picture as having some similarities to Jordan Peele-created smash hit "Get Out."

The movie was filmed this summer, meaning the best iPhone it could have been shot on was the iPhone 7 Plus.

Soderbergh's film isn't the first full-length to be shot entirely on an iPhone, but it may be the most high profile to date. In 2015, Sundance hit "Tangerine" was shot on an iPhone 5s, using an $8 app and an anamorphic lens accessory.

Soderbergh has a history of experimenting in film, using inexperienced actors, unconventional shooting methods, and unique release strategies. Some of his biggest hits include "Ocean's Eleven," "Erin Brockovich," "Magic Mike," and this year's "Logan Lucky."

According to Pharoah, Soderbergh's iPhone-driven shoot for "Unsane" lasted just over a week -- far shorter than a typical feature-length production takes to wrap. The director even began editing the film on set, letting the actors see a near-final product before they finished their parts.

"You wouldn't be able to tell anything [about how it was made]," Pharoah said. "It looks that great."

I wonder how audio is captured? I can’t imagine they just use the built in microphone...

The overwhelming majority of movies don't use audio recorded at the same time as the video. Instead, they typically have the actors dub their own lines in a studio. This gets cleaner audio with no chance of unexpected sounds from the set. That then gives the Foley artists greater control over the sound. Most staged TV, and even some "live" events like the Olympics, is done like this, too. There was a stink a few years ago when people realized the water sounds during Olympic rowing videos aren't actually from the event.

Probably a more traditional pro audio method, but I’d like to see the full equipment list eventually. Audiences remain receptive to movies with lower quality visuals as long as the audio is still good. If a great looking movie with poor audio is shown, audiences reject it immediately.

That really varies by movie and they usually only "loop" dialog that has problems, either technically or because of performance issues. In a film like the original Star Wars, almost every line was looped. But in many modern films, with improved miniature wireless microphones and the use of silent digital cameras, much original dialog is kept.
